A numerical diffusion model for continuous releases
article
The purpose of this study was to develop a diffusion model for a continuous point source which takes into account the increase of wind speed with height, and to compare this model with short-range diffusion experiments. The main problem was to find a good expression for the vertical diffusion coefficient. It turned out that good agreement between theory and experiment could only be obtained by introducing a settling speed W for the tracer combined with a conventional expression for the vertical diffusion (K(Z) = K0Z1-p). An empirical relation was found between K0 and τvU and between W and barσvU2. © 1973 D. Reidel Publishing Company.
